[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in the figure, the door and window frame profile extrusion molding cooling device of this embodiment includes a rectangular trough body 1, and also includes a profile guide structure arranged in the rectangular trough body, the profile guide structure includes a bracket 2 connected to the rectangular trough body by screws, a horizontal support roller 3 arranged on the bracket for supporting the door and window frame profile, and a transverse limiter arranged on the bracket and rollingly matched with the transverse edge of the door and window frame profile. In this embodiment, the transverse limiter includes a vertical shaft 4 and a rolling bearing 5 arranged on the vertical shaft; of course, in different embodiments, the rolling bearing 5 can also be replaced by a sleeve that rotates with the vertical shaft.

[0019] In this embodiment, the door and window frame profile extrusion molding cooling device also includes a water inlet pipeline and a drainage pipeline. The water inlet pipeline includes a water inlet main pipe 6, a water inlet branch pipe 7 and an outlet extension pipe 8. A plurality of water inlet branch pipes are arranged longitudinally along the rectangular trough body. The inlet end of the water inlet branch pipe is connected to the water inlet main pipe, and the outlet end of the water inlet branch pipe is arranged on both sides of the lateral side of the rectangular trough body. The outlet extension pipe is connected to the outlet of the water inlet branch pipe. In this embodiment, the outlet extension pipe is connected to the drainage branch pipe by a thread, and the outlet extension pipe can be easily disassembled and replaced. When producing different door and window frame profiles, the outlet extension pipe of a suitable length can be easily replaced; of course, in different embodiments, the outlet extension pipe can also be used: plugged into the drainage branch pipe in a telescopic manner, so that the extension length of the outlet extension pipe can be adjusted, and the cooling requirements of different door and window frame profiles can be conveniently met.

[0020] The drainage pipeline includes a drainage branch pipe 9 arranged at the end of the rectangular trough body and a drainage main pipe 10 connected to the drainage branch pipe.

[0021] like Figure 2 As shown, the door and window frame profile extrusion molding cooling device in this embodiment adopts a rotatable horizontal support roller to support the door and window frame profile 11, and adopts a rolling bearing to limit the door and window frame profile laterally, which can ensure that the door and window frame profile moves forward in a straight line, and there is rolling friction between the horizontal support roller and the rolling bearing and the door and window frame profile, so the friction resistance is small, which can avoid scratching the surface of the door and window frame profile.

[0022] In the door and window frame profile extrusion molding cooling device of this embodiment, the water inlet branch pipes are evenly arranged on both sides of the rectangular trough body, so that both sides of the door and window frame profile can be evenly cooled. The cooling water discharged from the water inlet branch pipe can be sent to the vicinity of the door and window frame profile through the outlet extension pipe, which can fully utilize the cooling capacity of the cooling water and avoid the cooling water being discharged along the edge of the rectangular trough body without being fully utilized.

[0023] As an improvement to the above embodiment, the two ends of the rectangular trough are respectively provided with rectangular windows and window covers 12, and the window covers are provided with profile passage openings 13 matching the outer contour of the door and window frame profile; in a specific implementation, the window covers 12 are connected to the ends of the rectangular trough by screws.

[0024] As an improvement to the above embodiment, the drainage pipeline further includes a seepage water recovery groove 14 provided at both ends of the rectangular trough body and a seepage water discharge pipe 15 connecting the seepage water recovery groove and the drainage main pipe. Since there is a matching gap between the door and window frame profile and the profile through-port 13 on the window cover plate 12, cooling water may leak from these matching gaps. By providing the seepage water recovery groove and the seepage water discharge pipe, the leaked water can be collected and discharged into the drainage main pipe, thereby keeping the environment around the cooling trough clean.

[0025] As an improvement to the above embodiment, the edge of the rectangular trough is hinged with a trough cover 16. The trough cover covers the mouth of the rectangular trough, thereby preventing dust from falling into the rectangular trough and keeping the rectangular trough clean.
